nEPArRrNG DEVICE.

To all whom t may concern:

Be it known that I, PETER HEDIN, a citizen ofl the United States,residing at Duluth,

in the county of St, Louis/and State of Minnesota, have invented certainnew and'useful Improvements in` Repairing Devices, of which thefollowing is a specification, referience being had therein to theaccompanyingjdrawing. v f This invention relates to a repairingfdeviceand has special reference to means forv the repair by solderingv ofmetalreceptacls or tel such as household hot water tanks like. y Y

The principal object of the invention is to provide simpleand convenientmeans wherey such soldering orjrepairing mayfbe ac-' complished withoutdismantlingor interfering withl therinstallation of the receptacle.Another object is to provide suoli a device which may be easily appliedrand operated by any person with ordinary skill;

Other objects and advantages'will appear in the further description ofthe invention.

Referring to the accompanying drawing forming part of this applicationand in which like reference characters indicate like parts:

Figure 1 is a front elevation of the principal body portion of thedevice.;

Fig. 2 is a central vertical sectionon the line 2 2 Fig. 1; and V Fig. 3is a broken top plan view of the device illustrating the manner in whichit is applied to a tank or receptacle.

1 represents the body portion of the device which is preferably composedYof a rectangularly shaped piece of wood, one face 2 of which is madeconcaved transverse the block. Centrally of this concaved surface is adeeper circularly concaved portion 8 which is surrounded, except at itsextreme uppermost ends, by a flat rubber gasket 4. The upper ends ofthis gasket are spaced apart and have diverging branch like pieces ofgasket 5 abutting therewith upon their circumferential edges, thus`forming a V- shaped entrance, as it were, to the concaved portion 3.The face of the blockrrl is cut away conically opposite this V-shapedopening, as at 6 forming the gate to the concaved portion 3.

Directly beneath the gate 6 andV inside of the gasket 4 is a channel orgroove 7 formed in the face 2 of the block and which groove iSpecification of Lettersy Patent. l

i Y extends from the concavedL .portion 3y to the lower edge oftheblock, this being for the purpose of discharging thesoldering material,during theinitial operationfof thedevice,lthe object of which will-.bedescribed later. J

VUpon either side of the groove or slot 7 are placed pieces' of rubbergasket 8 the samey n PatentedgAugrZS, 1921.`

Application led March 8, 1921. :Serial No. 450,600; l'

thickness and of flikematerialto that` of the y gasket 4, they being forthe purpose of confining-the. discharging material.

Within this :slot 7 Vand throughthe block 1 is formed a hole9 iriwhichismanually insertedA the blocklO,` said block having a rubber tip 11 onthe endv thereof whichcorresponds in thickness `to the gaskets 8.

For 4holding the block in position against an object. beingsoldered or`patched, the blockl is provided with two spacedl through holes12jthrough which a :suitable rope 13 is reevevd, fsaidrope beingdesigned to pass around? the receptacle or boiler *being patched, and,upon theA opposite side of they boiler, passed through: thev slidingnuts14. 'i

and 15 mounted upon the bolts` 16 and which boltis provided at `one endwith a suitable wing nut 17 which may be screwed up against the slidingnut 14, thus forcing the two nuts 14 and l5 toward each other pullingthe rope taut, the ends of the latter having been suitably tiedpreviously as at 18.

In operation the hole in the boiler, which is indicated at 19, is firstllocated andthe outside surface thereabout suitably cleaned, and, in theevent of the boiler being full of water at the time, a wooden plug,indicated at 20,V may be driven into the hole to st op the leak. Theblock l is then placed against the boiler with the hole as nearly as`possible occurring in the center of the concavedk the desired adhesiontakes place. ThentheA molten solder is poured into the gate 6 and willfollow down `against the surface to be patched and onout through vthechannel 7.

This pouring of the soldering material through the patch formingdevicefis contmued until such time as it 1s considered Vthat the surfaceof the boiler about the rupture is suiiiciently hot to resultin saidadhesion of the solder when the plugll Yis forced inwardly against thesurface of the boiler thus stopping the discharge ofthe material. Thenas the pouring continues the recess 3 `Will be completely filled andallowed to remain until cooled on". when the patch forming device Vmaybe removed -resulting in a neat circular convex patch, securely attachedoverthe rupture.

.From actual experience with suchifa device it is found v"thatfrequently three oiwfour patches of this kind may be made With oneof thedevices before it becomes suiiiciently burned or inJured to render itunuseful, and inasmuch as one such patch` may resultan the prolongationof the life of a boiler for` some considerable time the .method isconsidered an exceptionally profitable and feconomical advance in theart.

I Having thus describedmy.'inVention,:whatI claim and desire to secureby Letters Pat- 1.1 A patch forming device of theV character describedcomprising a body block, a concaved portion Within one face of theblock, a

recessed gate Within said face leading intoA said concavednportionthroughwhich to deposit soldering material to said portion and means forholding the block tightly against an object being patched.

2, A device ofthe class described comprising a body block, l.a concavedportion Within one face of the block, means surrounding said portionyfor ltorming a tight joint againstY an object to Which the block isapplied, a recessed gate in said block through Which to depositsoldering material .into .the

block, `a recessed filling gate Withinsaid face leading-intosaidfconcavcd portion, aire# ceSsed discharging gatewithin said-facealsocommumcating With said concaved fportlon whereby.V soldering'material-.may be passed through said recessed and conc'avedf portionsfor initially heating theLobj ect to be patched,

means-forv subsequentlyclosing the discharge v gate, and means forholding the block tightly against an obj ect being patched.
